“Zero Hour” data reflects the performance of a brand-new air compressor as engineered and first built. This is how rated capacity and energy consumption is documented and published for all air compressors.

However, very few manufacturers show "down the road" performance data. Why not? Because air compressor performance generally declines over time as bearings wear and tolerances deteriorate – and NOBODY wants to show that!

Well, Mattei is Simply Different. We don’t “screw around” when it comes to energy efficiency and performance. As time goes by, a Mattei vane compressor actually produces more air, consumes less power, and becomes more energy-efficient than when brand-new as the blades continue to season naturally during normal operation.

Below, you will find two styles of Mattei ImPROVable Performance data sheets that show the efficiency improvements that can ONLY come from rotary vane technology.

Fixed-speed compressors link to a single data sheet that incorporates both the “Zero Hour” and “500 Hour” performance data. Each fixed-speed class compressor (AC Series, BLADE Series, MAXIMA Series) displays performance data in a column entitled “Zero Hour” which shows a brand-new machine as first built then, the “500 Hour” column shows the efficiency gains you benefit with after the first 500 hours of operation.

Variable Frequency Drive style compressors incorporate a variety of capacity points which result in a much larger data table than a fixed-speed compressor. Therefore, we list a variety of data sheets segmented by pressure (PSI) for each model and provide separate links to the “Zero Hour” and “500 Hour” ImPROVable Performance ratings for each model and pressure.
